10,000-gallon. Jeff Wilson did a product review of this car in the February 1995 issue of Model Railroader. He built the kit version. He stated that the kit goes together well, that the wheelsets are in gauge, and that the model rolls very smoothly. It matches prototype dimensions, and it weighs the correct NMRA-spec weight. The four-digit product IDs are the hi-rail version of the same kit.
